Bulls eye levels are used to check the horizontal position of jigs, machines, devices, appliances and instruments.

This bulls eye level is adjustable. The mounting threads are offset by 120° allowing the spirit levels to be aligned in relation to the mounting surface. An alignment ball at the bottom surface of the adjustment plate serves as tilting point. The bolts can be tightened to specific torques, so that the bubble is located inside the marking ring once the horizontal alignment is reached.
